Jean-Loup Rouyer has a competitive clay court record of 44–37 across 81 matches (54.3%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Roland Garros): Jean-Loup Rouyer is 8–7 (53.3%) across 15 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

4 quarterfinals on clay, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

By format on clay — best-of-five: 10–12 (45.5%); best-of-three: 34–25 (57.6%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 1970 — 12–8 (60.0%) from 20 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
